Title: wells gardner ?
Post by: kjoel0123 on May 27, 2007, 12:06:52 pm

I just picked up a used wells gardner 25" model K7191. It requires an isolation transformer. I have a few sitting around but unsure what is correct for this model. Also does anyone know the correct voltage to the monitor. I know that if I put 120v to it will kill it. thanks

That model uses 120 VAC from an isolation transformer.

Thanks Ken .
Is this a special isolation transformer to use or will my other transformers work?

It's the conventional isolation transformer found in all American made games. These have a ratio of 1:1. In other words 120 volts non isolated in equal 120 volt isolated out.

Japanese made games (Nintendo and Sega in particular) have step down isolation transformers installed for USA power requirements. 120 volts non isolated in is stepped down to 100 volts isolated out.
